Just want to say, for those who are interested in color management as applied to monitors, let me recommend https://hub.displaycal.net/. It’s packed with exquisite technical information, if you are so inclined. You may even want to give their package a try – can’t beat the price, really. I requires some reading, true, but it’s all very good information, as far as I can see. Just head to their Help and Support or General Discussions Forums, reading what others have to say about their experience with calibrating and characterizing their displays will go a long way towards fostering a better understanding of the underlying technologies for yourself. Just one example, if I may. I used to work for a large printing company (I won’t name) and, one day, we were given monitors to put at each presses consoles. Wow! I thought. Crazy? At the same time. One of the advantage of the software we were using was its advanced understanding of monitor characteristics (which was never completely explained to me, even if I developed a good relationship with its author). We had to install some of these monitors at client’s sites too. And one site, who was very reluctant to jump aboard, where we had to install five such monitors, for color retouchers to use in Photoshop, day in and day out, insisted that we “prove” to them that our “technology” was good, meaning, we had to go to their offices, calibrate each of the five displays and then put them side by side, so that any differences could be compared. Well, I have to confess I did not know, at the time, the answer to this one, BEFORE spending some time reading this post, by Florian Höch, in the FAQ: https://hub.displaycal.net/forums/topic/frequently-asked-questions/ The issue is “How can several monitors can be made to match each other?” and Florian’s answer is very simple but proceeds from an intimate understanding of the technology: by forcing each display to a common “denominator”, it’s possible to physically match each other quite well. Which means, finding out what are ‘worst’ RGB and Black Point chromaticities and Luminances are, and then using that information to use as targets for the five displays. Seems so deceptively simple? Many of you, who are monitoring this list probably are very familiar with these proven techniques (and it’s not my point to teach you anything you already know) but it goes to show the worthiness of the information on DisplayCAL. Thank you so much Florian Höch and Graeme Gill – I’m obviously not working for these guys 😊 A big Kudo to you two. / Roger Breton www.graxx.ca
